This invention to him i. 2 has for in. ohjeo't hrs-ks 15.11 D made 12p apiurnliity of sections. The. sso'iions h rsniovahly secured to the swim hand simplby the turning of screws. in n coqanndin spplioation (355,285) I have (lB-Sfiilbfil inol generically removable hi'slislining ssginonis and means for clamping; or retaining them removahiy on the brake hand. This present application is ii'itsnclecl to cover a species of re mining nioans for holding the brains-iii in seg nnts roniov'ahiy on the brake hand.

These may he slipped into the pockets and. than the screws is turned down on the top of the hiake segment to jam them against the olisei; wings of the clip.

in Figs. '7 and 8 l have shown a modified.

ho cap screws form which, so far as the screws are con.-

cernecl, Works in the some Way as the form shown in 2 and 3, but in order to properly locate the hraks segment so a... cause same .10 propei-iy register wii'zh ii; hraks band, semi-spherical bosses m stamped in the metal backing of the hralste segment and these are adapted to slip into perforations n through the brake hanci. This insures the brake.- band segment prop srly lining up with the brake band and at the same time the tapped hole in ihe brake. segment backing-registering with the holethrough which the. screw is passed in the band.

What- I claim is:

1. in a brake. the combination of a. drum having a cylindrical braking surface, a hand provided with openings theretlnough and concentric with ihu braking surface 01"? "the drum, a' pluialiiy of brake-lining segments comprising each a backing in the form of a. segment of a cylinder and a niece of lining material seouied thereto, and screws passing ant and turning id of tapping the through the openings in the band and engaging the backing of the segments for removably holding the segments in place.

2.111 a brake, the combination of a drum having a brake band provided with openings therethrough and concentric with said braking surface, a plurality of cylindrical se ents comprising each a backing and a piece of lining material secured thereto but extending short of the ends of the backing, and screws passing through the openings H] the band and engaging with the exposed end portions hold the segments removably in the band.

3. In a brake.

provided with openings therethrouglna plurality. of brake-lining segments comprising each a backing lined with brake-lining material running short of the ends of the backing leaving exposed end? portions that are provided with tapped holes, and screws passing through the openings in the band and engaging the threads of the tapped holes for removably holding the brake-linlng segments to the band.

A. In a brake, the combination of a band cylindrical braking surface, a

of the backings of the segments to r rality of brake-lining segments com rising.

each a backing and having a piece 0 linin material secured to the face thereof, sal

backing provided with bosses ther n adaptl ed to engage some of the openings in the bandto cause the se ment to properly register with the ban through other openings in the band and engaging the segment backin'gs for removably securing the brake-lining segments to the band.

5. In a brake, the combination of a band provided with openings therein, brake-lining segments comprising each a backing and the combination of a band a' piece of .brake-lining'material secured thereto, each backing being provided with one or more bosses rising from the rear thereof and adapted to be engaged in one or more of the openings.in the brake band to properly line upthe segment with the band, and means for removably .securing the brake-lining segment to the band.

In testimony whereof I afiix my signature.
